Twitter’s growth is slowing. It only grew 1.4 percent from the third quarter to the fourth quarter, which is its slowest user growth quarter-over-quarter in the history of it being a public company.

The mixed bag of earnings results come after a month straight of Twitter developments. The company executed on some of the new products it previewed during Analyst Day in November: Instant, algorithmically curated timelines for new users, group private messaging, and “while you were away” updates. It made small forays into expanding its advertising beyond Twitter itself. Promoted tweets will start appearing on Flipboard and Yahoo Japan, the first partners.
